I need help finding the operating income (loss) if the changes are made.

Della Rain Gear selis monogrammed umbrellas on Etsy. Della Rain Gear is currently selling 500 umbrelas a month at a price of $28 per umbrella. The variable cost of each umbreta salf includes $12 to purchase the merchandise from suppliers and a $5 commission paid to Eisy. Fixed costs are $3,000 per month. The company is considering raising the selling price of each umbrella to $34, but believes the number of umbrellas soid would drop by 15% as a tecult of the price increase. Should Deila Rain Gear raise the seiling price of its umbrollas? Begin by preparting the contribution margin income statemtent at the current seliing price of $28 per umbrella. Next, cabculme Della Rein Gear's coperating income if the changes are made. (Use parenthites or a minus sigh for an operating lass)
